Diesel Engine Classification And Characteristics

According to the use of different diesel engines by horsepower, they can be divided into single-cylinder and multi-cylinder diesel engines. A diesel engine is an internal combustion engine that uses diesel fuel, converting the thermal energy released by fuel combustion into electrical energy or mechanical energy.

Generally speaking, diesel generator sets with more cylinders can reach higher maximum speeds and run very smoothly; while those with fewer cylinders have greater torque and can carry more weight. Multi-cylinder diesel engines are more expensive than single-cylinder ones, consume more fuel, and have higher power. Single-cylinder diesel engines have a higher probability of failure but are simple to maintain.

1.What are the working principle and application range of multi-cylinder diesel engines?

In a multi-cylinder diesel engine, each cylinder undergoes four processes in its working cycle: intake, compression, power, and exhaust. During the working cycle, only one stroke is the power stroke, while the other three are auxiliary strokes that create conditions for the working cycle. However, all cylinders do not operate simultaneously; instead, they have an as uniform working interval as possible. Therefore, the crankshaft of a multi-cylinder diesel engine moves evenly, operates stably, and can obtain sufficient power, making it widely used in the modern automotive industry. In addition, multi-cylinder diesel engines are also widely used in agricultural machinery, construction machinery, automotive industry, marine machinery, power industry and other fields.

2.What is the working principle and price of single-cylinder diesel engines?

A single-cylinder diesel engine, as classified by the number of cylinders, has only one cylinder. It mainly has two types: two-stroke and four-stroke. The two mechanisms are basically the same, with the main difference lying in the valve train. Each working cycle of a single-cylinder diesel engine goes through four processes: intake, compression, power, and exhaust. Since there is only one power stroke in one working cycle, the operation of a single-cylinder diesel engine is unstable. The development of single-cylinder diesel engines still relies on technological innovation, continuously adopting new technologies to improve the shortcomings and deficiencies of single-cylinder diesel engines and expand their scope of use. In terms of price, they are relatively cheap.

Diesel engines are mainly used in end-matching products, and diesel engines are one of the important components of diesel generators. For example, high-power high-speed diesel engines are mainly matched with heavy-duty vehicles, large passenger buses, construction machinery, ships, generator sets, etc. Therefore, the development of the diesel engine industry largely depends on the market conditions of related end products.
